BRUSH.

application filed August 25,

To all i /mm it may cone-om:

rcspectively at Hammond, in the count}: of 5e and State of Indiana, and Highland ark, in the county of Lake and State of lllinois, have invented new and useful Tmproveniients in Brushes, of which the foll wing is a specification. v

This invention relates to toilet brushes and more particularly to hair brushes of the type having handles and backs in the form of open frames and bristle holders made separate from said frames and fitting and secured in the under sidesthereof, the bristle holders being slot-ted so that water may be run through the brushes for keeping the same clean and sanitary.

One object of our invention is to provide means connecting the marginal portionsof the frame and bristle holder in a manner preventing the marginal portions of the frame from bending and spreading outward application of pressure on the brush when in use and thus avoid bending and cracking the handle at the juncture between the same and the frame.

A further object of our invention is to secure the holder in the frame by means avoiding the use of a plurality of bendable prongs on the frame.

The invention consists further in the matters hereinafter described. and more particularly set forth in the appended claim.

In the accompanying drawings Fig. 1 is atop plan view of a brush embodying the features of our invention, with a portion of the brush at the juncture of the handle and back broken away and in section to show a. detail of construction;

Fig. 2 is a side view of said brush with a part broken away to also illustrate a detail of construction;

Figs. 3 and t taken on lines and a e, respectively, of Fig. 1; and

Fig.5 is an enlarged vertical sectional view taken through theinterlocking portions at one side of the back and bristle holder and showing the securing flange of the former in position before being bent or rolled into the groove in the latter.

The brush shown in the drawings has a and carries a two laterally spaced are vertical sectional views 1921. Serial no. 495,380.

back in the form of an open frame 1 made substantially rectangular in shape and from one end of which projectsa handle 2 in the same plane of the back. The frame 1 and handle 2 are made integral and of metal by being cast in onepiece.

Thebristle holder 3 isalso made of metal and has the same general shape as the frame 1. Said bristle holder 3 is of the slotted type, as used in brushes of this general kind,

plurality of tufts of bristles 4, i, arranged in'rows and by a wire, as in brushes of this character. A. brush of this kind maybe readily and easily cleaned by placing the same under a faucet and running water through thesame, as is apparent. i I

As illustrated, the frame 1 has its side marginal portions 5 5 substantially parallel and with curved end portions 6, Tithe former being at the forward end of the brush and the latter at the opposite end and joining the handle 2. In the under side of these marginal portions 5, 6, and 7 is a clownwardly opening channel extending completely around the frame and receiving the marginal portions of the bristle holder The portions 8 of the channel in the side portions 5 5 are deeper than in the channel in the end portions 6, 7 and receive ribs or flanges 9. 9, one on each of the side portions 10, 10 of the bristle. holder 3, as shown. These ribsS), 9 project upward above the top surfaceof the bristle holder 3 and engage in said channel sections 8, 8 above that surface. Each channel section 8. 8 is formed between depending flanges 11, 12 one flange on the inside of the rib 9 and the other on the outside thereof. The ribs and flanges extend the full length portions of the frame 1 and bristle holder 3, respectively, and providean interlock between such parts along the tops of the bristle holder. The inside flange 11 is shorter than the outside one and engages against the top surface of the bristle holder 8 at the base 0 said rib on the inside thereof. Theoutside flange 12 extends downward over the outside of the side portion 10 and has its lower marginal portion bent or rolled inward against the side portion 10 and into a groove 13' provided therein for securing the bristle holder in the frame, as shown in Fi 3. The flanges 12 terminate Sl OTt 0f the rows of secured in nipples of the side nipplesat the sides of the bristle holder 3 and engage the bristle holder short of said nipples, thus avoiding the use of a connection requiring a plurality of tongues engaging under the bristle holder and between the nipples as heretofore employed.

The marginal portions of the frame 1 and bristle holder 3 being interlocked in the manner shown and described along the top J surface of the latter, the side portions-5, 5 or i the frame are held from bending or spread in'g outward from the bristle holder under the pressure applied on the brush Whenin use as in pressing the brush against the head in brushing the hair. This construction also strengthens and makes rigid the sides of the frame and prevents the handle 2 from hen '7 ing and cracking at the'juncture with tl 1e frame as it would if the frame were free'to bend outward at its sides.

To further aid in making rigid thejuucturebetWeenthe handle 2 and trail-1e l and prevent the handle bending and cracking at that place, We provide the bristle holder 3 with an integral tongue 14- at' its rear end and fitting in a recess 15 in the handle as shown in Figs. 1 to" 4. The tongue 14 is substantially flat and is arranged to extend transverse of the handle 2 so asto resist a pressure tending to bend and oracle the handle at the place mentioned.

aza /so lVhile We have shown and described here in in detail one formot ourinvention it to be of course understood that the details of construction may be variously changed and modified Without departing from the sp rit and scope of our invention and furthermore our invention may be applied to brushes having shapes different from that shown in the drawings.

We claim our invention A brush, comprising a back in the i of an open frame, and bristle holder 5, in the under side of said framer iaving upright ribs along the i thereof and with outwardly opeinag along the sides thereof below s: I frame having inner and outer o, i on flanges extending along the side margins thereoi said flanges bein laterally spaced apart to form channels for said ribs and gaging the latter along the inner and outer sides thereof the outer flanges extending to said grooves and having their lower man ginal portions bent inward into the same for securing saidholder in said frame and holding said i ribs in said channels. In testimony that We claim the foregoing as our invention, We afiir; our signatures, this 8 day of August, A. D. .1921.
